The PBT resin is crystalline thermoplastic polyester's resin.
The elastomer is a kind of ethylene-dien terpolymer.
The glass is alkali-free short glass fiber.
The fire retardant is brominated epoxy resin.
The flame retardant is antimony oxide.
The preparation method of above-mentioned new-energy automobile fiberglass reinforced high fire-retardance PC/PBT composite materials, step are：
(1) raw material is weighed by above-mentioned weight percent, be uniformly mixed, obtaining mixed raw material, (without glass, glass needs independent
Add)；
(2) dried mixed raw material is placed in the main feeding bin of double screw extruder, extrusion is added to through feed screw
In the main barrel of machine (screw diameter 35mm, draw ratio L/D=36), glass, the control that main barrel is respectively segmented are added in from side spout
Temperature processed (being exported from charge door to head) is：225 DEG C, 245 DEG C, 245 DEG C, 245 DEG C, 245 DEG C, 245 DEG C, engine speed is
300 revs/min, product is obtained after the processes such as melting extrusion, granulation, drying process.
By the fiberglass reinforced high fire-retardance PC/PBT composite materials of the new-energy automobile prepared by the present invention, both with excellent
Rigidity-toughness balanced performance, but also with high flame resistance, anti-flammability can reach UL94V0 grades, can be widely applied to new-energy automobile
Battery case component and electronic apparatus component etc. have greatly widened the application field of glass fiber reinforced PC/PBT material.
